"answer": "Postal bond ledger: (1) a new identity requests a physical card with a one-time code, sealed in a copper foil strip and mailed to a real address. (2) That code is signed on-chain, so one mailbox yields one identity, and the address map flags anyone who tries to wander into a second account from that cluster. (3) Each verified card stacks on a public, auditable ledge, so duplicates stand out. Forging 10,000 identities takes 10,000 mailings at $1.20 postage plus $0.40 handling: $16,000 and 30 days, all traceable paper. Faking a database row is cheap; faking a mountain of envelopes is not.",
